The ROK is one of the nicest manual espresso grinders on the market. The burrs and build quality are superb, making nicely balanced shots with lots of body. The long action crank makes it fast and easy to use (takes me 30-60 seconds to grind 18g). I have used it as my daily driver for about a year and a half. Accordingly, the grinder shows some wear but is in excellent working condition. The burrs are in great condition and are nicely seasoned. This is a very capable grinder, making fluffy and high uniform ground coffee even at extremely fine settings. While it can make delicious filter coffee, it’s designed for espresso and really shines when pulling shots. Please let me know if you have any questions!
